My Great Qin Cannot Die

charcoal!

Charcoal is a dark brown or black porous solid fuel that remains after incomplete combustion of wood or wood raw materials, or pyrolysis in the absence of air.

From the bronze wares of the Shang Dynasty to the iron smelting of the Spring and Autumn Period and the Warring States Period, charcoal was used, and its hygroscopicity was used to observe climate changes.

The firing of charcoal is very simple. There are basically two methods. One is the kiln firing method. The kiln is built with soil, filled with wood, and fired from the kiln door or fire door, so that the wood is carbonized in the kiln and the volatiles escape. out and the remaining charcoal.

The second is the dry distillation method, that is, the dry distillation of wood. There are two types of charcoal, black charcoal and white charcoal.

Although it is easy to burn, it is difficult to form charcoal, and the charcoal formation rate is too low. Most of them are six to one, or even ten to one. Moreover, "Zhou Li Yue Ling": in autumn, the grass and trees are yellow, and the salary is cut for charcoal.

It can be seen that if you want to burn charcoal, you must wait until autumn.

Naturally, it caused the lack of charcoal fire among the people, and even in the palace. If there is coal to replace, according to Ying Zheng, the coal mines in Pingcheng are very large.

If so, this will be a huge change for the Great Qin Empire.

The reason why Ying Zheng insisted on developing Yanmen County was because he learned from Li Kang's memory that the Pingcheng Coal Mine, or Datong Coal Mine in later generations, was the largest coal mine in China.

The reserves are large, and there are many mineable coal seams, with an average thickness of 30 to 40 meters. Low ash content, less sulfur and phosphorus impurities, high calorific value, and stable coal seam, easy to mine.

For Ying Zheng at this moment, the most important thing is that it is close to Xianyang, the capital of the Great Qin Emperor, and also has less impurities and is easy to mine. At this stage, the Daqin Empire has not yet entered the Iron Age, so naturally it can only mine easily mineable ore veins.

Moreover, the coal mines in Pingcheng were mined early in the history of later generations. Ying Zheng learned from Li Kang's memory that the "Shui Jing Zhu" written by Li Daoyuan during the Northern Wei Dynasty recorded in words the spontaneous combustion of coal seams in the Pingcheng area. and the development and utilization of coal.

By the Song Dynasty, coal was widely used as fuel in metallurgy, ceramics and other industries, and coal played an increasingly important role in the social economy. Coal was widely used in Pingcheng area.

During the Liao, Jin and Yuan dynasties, the coal mining industry in the Pingcheng area was very developed, and the iron smelting industry was also enduring, which promoted the development of the coal mining industry.

Until the Ming and Qing dynasties, coal in Pingcheng has been widely used in iron smelting, money casting, sulfur smelting, lime burning, brick burning, ceramic burning, winemaking, pharmaceuticals, black alum smelting, etc.

The information in Li Kang's memory made Ying Zheng make a decision immediately. He knew in his heart that the current Daqin Empire could only mine the simplest ore veins.

At the same time, this is also the reason why Ying Zheng decided to locate the first coal mine in the Qin Empire in Pingcheng.

The coal mines here do not require the technology of later generations, and can be mined by manpower, and the reserves of the coal mines in Pingcheng are large enough to satisfy the Great Qin Empire.

The most important thing is that Pingcheng has a special geographical location. It can use the straight road to transport coal to the maximum extent, enter Xianyang, and then pass through the Longbei Tunnel, Sanchuan Donghai Road, Hanoi Guangyang Road, Nanyang Nanjun Road, and Liaoxi Kuaiji Road.

In this way, the five main roads of the empire will be fully activated. Once in the future, charging points can be established to charge merchants' vehicles. In this way, the repair of the five main roads will not require money from the imperial treasury.

As the monarch of a country, one must consider all aspects, and the development of Yanmen County was a decision made by Ying Zheng after much deliberation. Of course, the development of Yanmen County is definitely not just about coal mines.

For the land reclamation and road construction in Yanmen County, things must be put on the agenda.

When it comes to building roads, Ying Zheng thinks of cement. If the cement is taken out, the road will be extremely durable.

It's just that Ying Zheng hasn't found out from Li Kang's memory about the firing of cement. Even if he wants to remind Shang Gongfang, he can't do anything.

This matter can only be delayed again and again to see if it is possible in the future, or in other words, Shang Workshop has researched it by itself.

Thinking of this, Ying Zheng quickly suppressed the wild thoughts in his heart. He knew in his heart that if it continued like this, he would think about it for a day, and it would not end.

"Zuo Prime Minister, I called you this time to mention the development of Yanmen County. After going down, the government office will send someone to Yanmen County to go to the countryside together with the governor of Yanmen County to learn about it, and then formulate a plan. Yanmen County Development Plan.”

"promise."

Seeing Ying Zheng attaches great importance to it, Wang Wan nodded: "Don't worry, Your Majesty, this minister will personally go to this matter to make sure nothing goes wrong!"

At this moment, Ying Zheng looked at Wang Wan with a burning gaze: "Let Xiao He go, you are still in Xianyang, you are not here, Li Siyuan is in Sanjin, I am afraid it is Xiao He and Xiang He can't handle it."

"The old minister understands!"

Ying Zheng still had great faith in Wang Wan's ability. After all, he had been in charge of the Qin Empire for many years, and he already had experience in some things.

At this stage, although there will be changes in Daqin, the basic plan should still be based on stability.

Wang Wan left the study~www.wuxiaspot.com~ Ying Zheng walked into the bedroom, he was a little tired and needed to rest for a while.

Today's Daqin Empire's decision-making cannot be negligent in the slightest. He is the most critical emperor, and must be recharged. Only in this way can he make the most tactful decision.

...

Doctoral Palace.

Although today's doctoral palaces no longer have the qualifications to participate in political affairs, they are still an official office, an official office responsible for revising history.

Since Chunyuyue was beheaded by horse thieves, the Confucian people have temporarily settled down.

"Brother Fu, when will we be the best in our day? Now, people in the world may have already forgotten us!" Mao Jiao's eyes were deep, and he was obviously very dissatisfied with the current situation.

He came to Daqin to stand out, not to cultivate history in obscurity.

"Now that His Majesty is pushing the remnants of the Six Nations, Dading in the Central Plains, and the land reform has reached the land of the Three Jins. If we, such as the people from the hundreds of schools of thought, are not knowledgeable, the next ones to open the knife will be the people of the hundreds of schools of thought."

Shusuntong shook his head, seemingly insipid, but the sarcasm in his tone was too obvious.

In Shusuntong's view, the reason why the official office of the Doctoral Academy has been reduced to today's situation is that Mao Jiao, Chunyuyue and others committed suicide.

After all, the First Emperor Ying Zheng has always treated them extremely favorably, and even if they pointed at the meritorious generals above the court, the Qin Dynasty would not fight back.

However, Chunyuyue and others wanted too much, and they met a peerless and powerful emperor. Now most of them are able to live because of the kindness of the first emperor.

As a result, at this time, there are still people who are unwilling and want more power. In the face of a domineering emperor like the First Emperor, he is really not afraid of doom.
